Q. When undergoing an X-ray or cat-scan which requires being alone in a room with the female technician, what should one do to avoid transgressing the prohibition of yichud? Even if one’s wife or friend is with him, they cannot be in the actual room due to harmful radiation.
A. Horav Shlomo Miller’s Shlit’a opinion is that one may be lenient, since the procedure can usually be examined by others via the observation window and video cameras are also common in hospitals in our days. Besides doctors and technicians often go by and may just view the proceedings via an open or partially open door.
